Minilaparoscopy in the diagnosis of cirrhosis: superiority in patients with Child-Pugh A and macronodular disease.

Background And Study Aims: The diagnosis of cirrhosis has prognostic and therapeutic implications, but early forms are difficult to diagnose. Laparoscopy with histology has been reported to be superior to histology alone, but is often considered to be too invasive. This study aimed to assess whether minilaparoscopy offers similarly high sensitivity coupled with only minor invasiveness.

Patients And Methods: Minilaparoscopy with biopsy was performed in 226 consecutive patients with chronic liver disease. Cirrhosis was diagnosed macroscopically primarily on the basis of nodularity in a nontumorous liver. A histological diagnosis using the modified Knodell score was made without knowledge of the macroscopic assessment.

Results: Biopsies from 22 patients were inadequate for histological assessment, and 16 of these were considered to be cirrhotic from macroscopic observation. Out of 204 liver biopsies, 94 (46 %) were macroscopically identified as cirrhotic; 68/204 (33 %) showed stage 5 or 6 fibrosis (incomplete or complete cirrhosis). Histological understaging occurred mainly in patients who were otherwise diagnosed as having early Child-Pugh A cirrhosis, macroscopically incomplete cirrhosis and macronodular cirrhosis; 4/204 (2 %) of patients with cirrhosis histologically were understaged macroscopically.

Conclusions: Macroscopic evaluation during minilaparoscopy increases the sensitivity of detection of liver cirrhosis, compared with biopsy alone, by more than 30 %. Because of its minimal invasiveness, minilaparoscopy combined with biopsy is recommended as a superior method for the staging of chronic liver disease.
